On the 88f6183, orion5x's setup_cpu_win() fails to ever program any
mbus bridge remap registers, which causes transactions for PCI/PCIe
IO/MEM space to get sent to random mbus targets. Adding a check for
the 6183 in orion5x_cpu_win_can_remap() is necessary and sufficient
to make PCIe wlan cards work on the 6183 reference design.

If IRQ triggering is enabled, it can trigger a pending interrupt
even for masked interrupts. Any pending GPIO interrupts can
prevent the powerdomain from hitting retention.

This patch causes the OMAP uarts to honor the sysfs power/wakeup file
for IOPAD wakeups. Before the OMAP was always woken up from off mode
on a rs232 signal change. This patch also creates a different
platform device for each serial port so that the wakeup properties can
be control per port.
By default, IOPAD wakeups are enabled for each UART. To disable,
# echo disabled > /sys/devices/platform/serial8250.0/power/wakeup
Where serial8250.0 can be replaced by .1, or .2 to control the other
ports.

It was possible for an unhandled interrupt to occur if there was incoming
serial traffic during wakeup from suspend. This was caused by the code
in arch-arm/mach-omap2/serial.c keeping interrupt enabled all the time,
but not acking its interrupts. Applies on top of PM branch.
Use the PM begin/end hooks to ensure that the "serial idle" interrupts
are disabled during the suspend path. Also, since begin/end hooks are
now used, use the suspend_state that is passed in the begin hook instead
of the enter hook as per the platform_suspend_ops docs.

commit 6321e3ed2acf3ee9643cdd403e1c88605d7944ba caused
the full bmv_count's worth of getbmapx structures to get
allocated; telling it to do MAXEXTNUM was a bit insane,
resulting in ENOMEM every time.
Chop it down to something reasonable, the number of slots
in the caller's input buffer. If this is too large the
caller may get ENOMEM but the reason should not be a
mystery, and they can try again with something smaller.
We add 1 to the value because in the normal getbmap
world, bmv_count includes the header and xfs_getbmap does:
nex = bmv->bmv_count - 1;
if (nex <= 0)
return XFS_ERROR(EINVAL);

Prior to the change for more sane end_io functions, we exported
the helpers with the normal EXPORT_SYMBOL(). That got changed
to _GPL() for the new interface. Revert that particular change,
on the basis that this is basic functionality and doesn't dip
into internal structures. If these exports can't be non-GPL,
then we may as well make EXPORT_SYMBOL() imply GPL for
everything.

Move the assignment of a default lock below blk_init_queue() to
blk_queue_make_request(), so we also get to set the default lock
for ->make_request_fn() based drivers. This is important since the
queue flag locking requires a lock to be in place.

We cannot acknowledge the sector write before checking its status
(which is done on the next loop iteration) and we also need to do
the final status register check after writing the last sector.
Fix mg_write() to match mg_write_intr() in this regard.
While at it:
- add mg_read_one() and mg_write_one() helpers
- always use MG_SECTOR_SIZE and remove MG_STORAGE_BUFFER_SIZE
